= LONG ISLAND CREEK SITE 6B = = CONCLUSION =

Long Island Creek Sites 6A and 6B are located in the Chattahoochee River National Recreation Area Palisades unit. There are very few manmade structures and improvements in the immediate area of site 6B barring a foot bridge and several unpaved footpaths. This site is approximately 228 feet from the mouth of the creek as it flows into the Chattahoochee River and is downstream of site 6A. The stream ran clear during the dry periods and slightly turbid the day following heavy rainfall as was expected. Chemical testing showed in-range pH, DO, nitrate-Nitrogen, and phosphate levels for Georgia streams given the current temperatures. The bacterial water testing proved to contain higher counts of coliforms and in corresponding high concentration E coli. from the sample tested the day after a heavy rain, with significantly lower counts the following weeks which saw no rainfall. All readings indicate that the water bacterial levels were too high for safe swimming according to the US EPA. In all samples, the water tested in the area of neutral pH and a consistent finding of dissolved Oxygen given the water temperature for all tests conducted. Nitrate as well as phosphate testing showed near 0. The trees inventoried as representative of the riparian area of this stream segment showed a majority of Yellow Poplars with a mix of different species of oaks and other hardwoods. Most were healthy with the exception of those taken directly on the stream bank which had some exposed roots due to undercutting.

Additional collection, testing and analysis of stream data for an extended period would be necessary for useful statistical analysis.
